Aglaonema plant named ‘OSVAG2’

ABSTRACT

A new and distinct  Aglaonema  plant having pink and green colored leaves and pink colored stems.

Botanical classification: Interspecific Aglaonema hybrid.

Varietal denomination: ‘OSVAG2’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety of Aglaonema plant having the varietal name of ‘OSVAG2’. ‘OSVAG2’ is the result of a cross conducted in Costa Rica between Aglaonema hybrid variety known as “Diamond Duke” (female parent, unpatented) and Aglaonema hybrid variety known as “Starlite Simone” (male parent, unpatented). The new variety was selected in August of 2018 in Costa Rica. Asexual reproductions of the new variety by cuttings first occurred in April of 2019. The new variety is similar to its female and male parents in leaf midrib, stem, and petiole colors. However, “Diamond Duke” exhibits less leaf variegation and coloration spreading from the midrib than ‘OSVAG2’. Further, the leaf venation of “Starlite Simone” is more pronounced than that of ‘OSVAG2’. ‘OSVAG2’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

Similar to an unnamed and unpatented Aglaonema variety known to the breeder, ‘OSVAG2’ exhibits pink and green colored leaves, pink colored midribs and stems, and green colored leaf margins. However, the varieties differ in that the leaves of the comparison variety are narrower, have more pink coloration spreading from their midribs, and have more outlined venation. When compared to Aglaonema variety named ‘OSVAG1’ (U.S. Plant patent application Ser. No. 16/924,357), the new variety is similar in leaf size and shape. However, ‘OSVAG1’ exhibits red and green colored leaves. Further, the following characteristics distinguish ‘OSVAG2’ from other Aglaonema varieties known to the breeder:

-   -   Pink colored stems and petioles;     -   Green colored leaf margins;     -   Leaf midribs that transition from dark pink to green coloration;         and     -   Venation that differs from pink to green in color.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings taken at approximately 18 months of age illustrate the new variety, with the colors being as nearly true as is possible with color illustrations of this type:

FIG. 1 shows a plant of the new variety;

FIG. 2 shows a close-up view of the foliage of multiple plants of the new variety; and

FIG. 3 shows a close-up view of the upper leaf surface of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety at approximately 18 months of age. The data which defines these characteristics was collected in a greenhouse in June of 2020 in Miami, Fla. Plants of the new variety were grown under 2,500 foot candles of artificial light in 2 gallon pots in a greenhouse in Miami, Fla. having 70% relative humidity and average temperatures from 18-29° C. Color references are primarily to the Munsell Plant Tissue Color Book, 2019 publication, except where general color terms are used.
